## Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1820 would be equivalent to £0.89 in 1828, an absolute change of £-0.11 and a cumulative change of -11.11%.

Compare these numbers to the US's overall absolute change of \$-0.19 and total percent change of -18.80%.

## Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes.

This chart shows the average rate of inflation for select CPI categories between 1820 and 1828.

Compare these values to the overall average of -2.57% per year:

## How to calculate inflation rate for \$1, 1820 to 1828

Our calculations use the following inflation rate formula to calculate the change in value between 1820 and 1828:

CPI in 1828 CPI in 1820
×
1820 USD value
=
1828 USD value

Then plug in historical CPI values. The U.S. CPI was 11.7 in the year 1820 and 9.5 in 1828:

9.511.7
×
\$1
=
\$0.81

\$1 in 1820 has the same "purchasing power" or "buying power" as \$0.81 in 1828.

To get the total inflation rate for the 8 years between 1820 and 1828, we use the following formula:

CPI in 1828 - CPI in 1820CPI in 1820
×
100
=
Cumulative inflation rate (8 years)

Plugging in the values to this equation, we get:

9.5 - 11.711.7
×
100
=
-19%
